182 MILES

My 01 CRV started running a little roughly and when I accelerated, it ran fine, but as soon as my foot was off the gas, it would start to decelerate, almost like a brake was hanging up somewhere? I took it in and the dealer raised the idle speed. I ended up having to use mid grade gas to keep it running properly. They said the brakes were all fine. It has continued to get gradually worse on the feeling that it wasn't moving forward easily if the gas wasn't being pressed.

A couple of days ago, my husband started to drive it and said it wouldn't move and the check engine light had come on. I drove it to the mechanic and got there fine although it was definitely dragging more. The next morning, the mechanic tried to take it for a test drive and couldn't get it to move hardly, so he pulled it in and put it on the hoist and found that the catalytic converter was redhot. Apparently part of my exhaust had collapsed and the catalytic converter was clogged and everything was really caboned up and the plugs were fouled. He replaced the entire exhaust (it was original) and did an oil change and replaced the spark plugs.

I picked it up yesterday and when I put it in reverse to leave, the idle went way down and the lights dimmed and then the idle bumped back up a little. The new exhaust was rattling too, which is something else. Anyhow, I had the mechanic get in and try it and it did the same thing. We took it for a little ride and the acceleration is excellent again, but at low speeds, it dies and the check engine light has come back on.

What do you think? I appreciate any help you can offer!

If the check engine light is on, having the computer scanned should identify where the problem is coming from. Most parts stores will di it for free. As far as the idle, check the idle air control valve (IAC).

Thank you. My post should say 182,000 miles. I wonder if my mechanic has a computer that does this. It's an old fashioned small town shop.

Would the fact that my car has been getting starved for air over a long period because of the exhaust issue, contribute to the IAC being the problem?

The exhaust glowed red hot because the engine was misfiring and that caused it to malfunction.

If you don't have a scan tool to check the trouble codes, it can be done with manual methods. Let us know if it is required.
